Well firstly thank you for the T-line suggestion, after looking in my current case I really dont think I have room for a res in it (Not to mention there is really no place for the rad but I can mount that externally, strangely enough the 30.00 case I bought has tube access on the back panel for tubing.) Also ... I saw some "radiators" that look exactly like the modded Chev HeaterCore. This one looks very similar. and it says "80 mm (3 inch) Copper core consisting of flat tubes for maximum heat conductivity" Im guessing the flat tubes are like the fins in the HeaterCore. I dunno ... the HeaterCore you said cost about 25.00 USD and Im looking at at least 10.00 USD for the supplies to mod it (I have acess to a tourch and the infinant wisdom of a hardware store so I will have help soddering the Male ADPTs). Tell me what you think about what I linked up there
